Long Term Aquatic Monitoring (LTAM) pebble count summary data and individual working data, 2006-2017, in support of the Cedar River Watershed Habitat Conservation Plan, for Seattle Public Utilities in North Bend, Washington. Field methods were based on Wolman Pebble Count methods, e.g. using the blind touch method off the tip of the boot and measuring intermediate b-axis for at least 100 particles, bankfull to bankfull, for all channels at a particular cross section. Data is summarized for each cross section for each year at each site, as well as all cross sections for each year at each site, into particle size class distribution classes and noting p-value significance.
